“The father, Reginald Campos, then went out in his own SUV and found the men. “
I agree that the father went out looking for trouble. It was probably a case of the father getting angry and emotional thinking someone was stalking his daughter. Being a father of girls I can understand this. Going and and trying to find the alleged stalkers and reporting them to police is one thing. Confronting them (which I assume is what happened) is another matter.
That's when the firearm is best left at home.
